I have had up to 6 different linux OS's installed at one time. There is really nothing to be concerned about, except for the bootloader location.
My first recommendation is that you download the SuperGrub2 .iso and burn it to a CD. That way you will always have a way to repair your Grub, or boot any of your operating systems.
You have 2 choices for installing the bootloader (Grub).
1) Install Distro1's Grub to the device (/dev/sda), and then install all subsequent bootloaders to the partition where that OS is installed. That will preserve Distro1's control of the Grub menu. You would refresh the Grub menu (to add new OS's) by booting into Distro1 and running sudo update-grub.
2) Install each OS's Grub to the device (/dev/sda) during installation. When you do that each new OS will then control the Grub menu. If you want Distro1 to always control the Grub menu, you would boot into Distro1 and run both commands, sudo update-grub, and sudo grub-install /dev/sda (to re-install Distro1's Grub)
This is my preferred method. I am not a fan of installing Grub to a partition.
If Distro1 is Ubuntu or Linux Lite, both use Grub2. If you install PCLinuxOS, which uses the old Grub, (not Grub2), you will have a Grub menu which will not automatically detect your other OS's which use Grub2. So you will end up with a Grub menu which lists only PCLinuxOS.
This is where your SuperGrub2 CD becomes invaluable. When you boot that, and chose the "Detect any Operating System" menu item, the program will search your drives for your installed operating systems and create a menu for you that will allow you to boot any one of them. It will be a slow process to search your drives and create that menu, so be patient and let it complete.
Then after you use that menu to boot into your Distro1, run the following commands in a terminal:
Then Distro1 will be back in control of the Grub menu, and all other OS's should be listed (including PCLinuxOS).
